Chemical Bonds

Naming Bonds

REMEMBER WHEN NAMING COVALENT BONDS

• Mono = one Di = two Tri = 3 Tetra = 4 Penta = 5 Hexa = 6 Hepta = 7 Octa = 8 Nona = 9 Deca = 10

Multiple Choice

A simple compound is

• only 2 elements and 2 subscripts

• only 2 elements

• only 2 elements and 2 suprascripts

Multiple Select

Use the PREFIXES (mono-, di, tri-, etc) when naming..

• Covalent bonds

• Ionic bonds

• Diatomic Atoms

• Elements

Covalent Bonds...

• Differ from ionic bonds because they SHARE an electron

Poll

Ionic bonds represent

• The transferring of valence electrons

• The sharing of valence electrons

In naming Ionic bonds...

• You ALWAYS use a roman numeral to represent a suprascript

• You NEVER use a prefix

DON'T FORGET YOUR -IDE!!!!!!

:) THIS GOES FOR BOTH BONDS!

Why?

This is because we have the SUBSCRIPT of 2 and 3 that we MUST represent. Stay confident even if you got it wrong. Let's practice another one.

Who put water?

:)

If I asked you to tell me what this compound is water would be correct. However, I am not asking that, I'm asking you to NAME the compound.

STAY CONFIDENT! THIS IS HARD STUFF!

Multiple Choice

Ok now for an easy one.. name the compound NaCl

• Sodium Chlorine

• MonoSodium Monochlorine

• Monosodium Monochloride

• Sodium Chloride

But Mrs. Sawickiiiii why?!

That was an IONIC compound

• HOW ARE WE SUPPOSED TO KNOW THAT????

• Trust yourself you know more than you think you do!

• Let's break it down..

Sodium = Metal Chlorine = Non-metal

Multiple Select

Now, a COVALENT bond forms between what?

• A non-metal

• A metal

• Another non-metal

• Another metal

Poll

So NaCl is..

• Ionic

• Covalent

Let's learn another trick to tell covalent and ionic bonds apart.

Now let's try to name some IONIC compounds.

Remember this is the Roman Numerals!

Any Questions??
